| Research Abstract |
In this research, we have developed a sensing device with high sensitivity for bio-signals measurement based on the piezoceramic. By attaching the four sensing devices under the legs of the ordinary bed respectively, it is possible to measure heartbeat, respiration, snoring, body movement, turning over and scratching motion of the person lying on the bed without any attaching sensor on the body.
Furthermore, regarding the scratching motion, we proposed the automatic extraction method for Total Scratching Time (TST) which is correlated to the degree of pruritus in skin diseases such as atopic dermatitis. Since the high sensitivity sensing device could measure vibrations generated by scratching motion with high SN ration, it is possible to automatically detect TST with high accuracy unconstrainedly.
